My advice in addition to communing with nature is to let go of your ssd.
That's right.
As long as the bully despots know they can hurt you with it they will hold it hostage. Don't give them the satisfaction. Show them they have no power over your happiness, mental stability or income stream. They will get bored of bullying you. Even if they eventually return your property, I would wager it will be rendered useless to you one way or another. ("accidentally" erased/corrupted or physically destroyed.) Best for your sanity to consider it gone. If it does come back then won't that be a pleasant surprise!
In the meantime, I suggest you stick it to them by re-creating your data from scratch and move forward. A arduous task I know, but the product will likely be better than before since your skills will have progressed. I bet your the majority of you patrons and buyers will support you in this endeavor (I am buying MNM as soon as the purchase button goes back up). But this time you'll be prepared by keeping frequent physically offsite backups to prevent future loss. Not just in the cloud. Big Tech companies are well known for collaborating with governments to violate peoples' rights.
Get satisfaction from your life first then your work and also importantly, your fans. Never allow your happiness, sanity or income stream be controlled by anyone else again. Self sufficiency will set you free and you will forever more be in control of your destiny. Communities will thrive when they stick together and support each other. This is true not only for our local communities, but also virtual/online ones based on shared interests etc.
Power to the people through individual freedom!
Go fourth and prosper my friend.
